As the subject suggests, i pulled down my untouched 998 block today and the interal walls of the block and everything not machined or touching something has been painted! Has anyone else found this?
what does it mean??

Yes i have seen that previously - used to be done on race engines as a way you keeping them looking clean for rebuilds etc.

It does mean that your untouched 998 has been previously touched.

Mike

mmmm will double check some bits and pieces later on and see what it was

Racers used to use it as a means to stop oil clinging to metal where it is doing nothing. Effectively making the return to sump quicker than normal. The parts have to be prepared meticulously and I believe the paint is formulated specifically for purpose. Any flakes could present all sorts of problems if/when ingested by the oil system.

There is also a theory about painting the water galleries to help conduct heat and prevent rusting.

the paint on the internal walls is definately on well with no flaking anywhere, when i get this hot tanked for the rebuild will it remove all the old paint or will it remain? is it going to cause problems because i have other blocks i could use if this one will pose a problem,
I also checked the pistons i removed from the block and they were all marked with an A pointing to the front of the car and the following sequence of numbers etc.. FRONT M2039 A14
any ideas
I dont have any way of measuring the bores etc at the moment so im thinking ill take the crank with me when i go to the machine shop and have them check the stroke.
But the piston compared with the ones i took out of my 1100 are definately very different in they have longer skirts and not quite as dished to the standard 1100 pistons. putting them top to top they appear the same size.
got me puzzled so ill be hoping someone here can shed some light on it for me.
Cheers
Nicho

What colour is the paint? A lot of early UK blocks (and heads) were painted with red oxide at the foundry.

That could be it. The color is red and I would say red oxide if I was describing it.

Ditto above post....

I bought an 1100S block late last year that had never been apart before.....
and inside painted green like picture above...

The paint they used must have been pretty good. The engine out of my J type van is 61 years old and the paint inside is still OK. On the outside its absolutely stuffed.

This stuff is supposed to do the same job.

During my trade training, we were told to always "seal" internal casting faces to prevent sand coming loose from the casting process and to also assist with porosity problems. Apparently, sand could still be dislodged after many years, aggravated by acid bathing etc.

Al

Casting sand is a major source of minis over heating when they chuff around on forty odd year old radiators. It gathers in the radiator tubing and helps collect the other sludge that is in the coolant system.

It just comes away a grain at a time over the years until there is a fair deposit. Less of a concern in the oil system as it tends to be collected in the oil filters.

A good reason to get radiators "rodded" out before summer.

Mike

Mike, sand is more of a concern in the lube system because the filter is only one component, it all goes through the pump first.

Al

True - but it doesn't seem to cause as many problems (in the long term) as the build up of crud in the radiator.

I think they may have been more careful with the oil galleries at machining time.
